To all 'whom z'tmag/concer/IL:

Be it know-n that I, yJorrit` BLUE, a citi# zeno the United States, residing atLaurinburga inthe county oi Seotland and?y State o'tNorth Carolina, have invented anew and useful Fertilizer Distributor, ot'-v which the 'following is a' specilication.

This invention relates to fliertili zeri distrib1 utors. y

An object of the present invention'- is to provide an improved gear shifting mechanism for implementsofthisoharaoten A `turther object is to vprovidefan improved stirring means and a mounting therefor.

Other objects `are tol improve .generally the construction ottertfilizer. distributors so that they are more readily adapted. for service under varying conditions, and. so' that they doitheirA Work more e'fieiently.

yllhe inventionr Will be best understood 'from a consideration of the following detailedv description taken. in. connection with the accompanying drawing forming part' of this specification, with. ther i'lnderstanding, however, that.A the invention isnot confined to anyA strict. conformity. with the showing in the drawing, but may: be cliangedgand modified so long asA suclrchanges and modi- {ications mai-lino material7 departure from the salient features oiiftrlier invention asf expressed` in the appended; claims.

'The arms A33 `.extend in lines nearly parallel to the shaft 31these arms Ybeing designed to exert The arms 33,as sho'wmvare much shorterthan thearms34. @The latter arms engage withv the worin V'whereby the stirrer is rotated.

' The arms 34 extend alternately in directions.

to thelleft and to the right of the hub 32 on opposite sides :of the axisof the. Worm.

Every other arm 34 has aV` beveled end 34a, thisbevel beingfnecessary because the ends of ysaid arms engage with thehelical surface l oftheworm. This worm, being preferably -cast,-may have' smallV imperfections inY its surface which'would tend tobreak or bend those arms providedwith the beveled ends.

The huh ofthe bull wheel is extended as indicated at .41. Obviously, when the rod 47 isV turned on its axis by the operator, theeccentric 51 will be'revolved so asito carry the shaft 24 with its beveled gear -away from the gearteeth on the bull wheel. AThe bracket54,. While shiftable or adjustable, is in leffect a fixed support; that is, itv doesnot move ywhen the rod 24 is moved. 1 I;YV Y Thegear shift permits the operator to temporarily stop the distribution ofthe fertilizer, as whendriving toor. from the rfield or in making turns. lhatever the position of the gear'351along the Vshaft'24,

is `vreadily effected.' .The stirrer-jinsures proper feedyof'the fertilizer to the screw conveyer, while the latter, becauseof itsr increase in size'in 'the directionof its feed, prevents the fertilizer Vfrom caking. The implement distributes its fertilizer evenlyv and uniformlyl at any desiredrate', iseasly handled: 'andv transported, andV i'sfreadily' adapted to serve-'under all conditions.
